FIG. 7

(Left) Two dimensional Spontaneous Raman (2DSPR) spectra of WY dipeptide with excitation energy scanned from 36000 to 48000 cm−1. (a) and (b) horizontal slices excited at ω1=232 and ω1=270 nm, respectively. Vibrational mode assignment as listed in Table II. A nonlinear scale function Eq. 13 is used for better visibility.
